Millions of birds are killed each year in cities when they strike lighted buildings, especially ones covered with a lot of glass. Experts say artificial lights at night are confusing for migratory birds. They often run into glass buildings — not knowing the light is on the other side.
“There is a bird here, a woodpecker.” Lisbeth Fuisz is the director of a campaign called Lights Out DC. Volunteers often walk around the sides of buildings, collecting fallen birds before they are eaten by predators or swept away by cleaning crews.
Lisbeth Fuisz says the area has many buildings that give a danger to migrating birds. “Large areas of glass are lit at night, which have plants inside the building. Because the bird sees the plant in the building, it doesn't see the glass and runs into the windows. And they are attracted to the lights.”
The Lights Out DC campaign asks building owners to turn off unnecessary lights at night during peak bird migration periods, in the spring and fall. “There are a lot of advantages flying at night, fewer predators. There is less heat change so that they can fly more easily. They navigate using the stars.”
Lisbeth Fuisz also says one of many federal office buildings has agreed to their request. “Since they've done that, we've seen a twothirds reduction in the amount of bird fatalities at that site.”
The birds are identified, frozen and photographed. “The purpose of collecting birds is to have proof that there is a problem. And that is also why we photograph the birds.”
The birds are sent to the museum. Brian Schmidt said, “Researchers can look at carbon and nitrogen marks and they can determine where these birds hatch, where they grow up, and why they are coming through our part of the country.”
